Airsoft Guns vs. BB Guns vs. Air Guns: What’s the Difference?

Whether you're looking for a safe way to introduce teens to shooting sports or just curious about the world of air-powered guns, chances are you’ve run into a lot of overlapping terms, like airsoft, BB, pellet, and air rifle. It’s enough to make anyone pause before clicking “add to cart.”  We’re here to break it all down so you can find which option might be right for your needs.

Overview of Air-Powered Guns

Air-powered guns fall into three main categories: airsoft guns, BB guns, and air guns (often used as shorthand for pellet rifles or air rifles). And while they may look similar at first glance, there are differences that can affect everything from how they fire to who should use them.

Here’s a quick breakdown

• Airsoft Guns originated in Japan in the 1970s. They’re now used worldwide in recreational and tactical uses.
• BB Guns have roots going back to the late 1800s, originally designed for marksmanship training.
• Air Guns, often referring to pellet rifles, have been used for small game hunting, target shooting, and sport competitions since at least the 16th century. They're the most powerful of the three.

So yes, they’re all “air-powered”. But that’s about where the similarities end. Let’s start by taking a closer look at the most beginner-friendly of the bunch: airsoft.

What is an Airsoft Gun?

How Airsoft Guns Work

Airsoft guns fall into three main categories based on how they’re powered:

Spring-powered airsoft guns are simple, affordable, and ideal for beginners or casual backyard shooting, as they require manual cocking before each shot.

Gas-powered models use CO2 or green gas for propulsion, offering semi-automatic or full-automatic fire with realistic recoil.

Electric airsoft guns (AEGs) are battery-powered, known for their rapid fire, upgradeability, and popularity among airsoft players.

Airsoft Ammunition

Airsoft guns use 6mm plastic BBs, which come in various weights and materials. Here’s a quick overview:

• Standard ammo (0.20g – 0.30g): The most common and balanced for accuracy and range.
• Lightweight ammo (0.12g): Inexpensive but not ideal for high-end guns due to wind drift and poor accuracy.
• Heavy ammo (0.32g – 0.50g): Used for sniper or high-powered rifles for precision.
• Alternate sizes: Some specialty guns use 8mm.
• Biodegradable BBs: Required in many fields, check out the selection here if you want to stay eco-friendly and game-ready.

Common Uses for Airsoft Guns

• Recreational play
• MilSim events
• Training scenarios

Airsoft Gun Safety & Legal Info

Airsoft is designed with safety in mind, but that doesn’t mean it’s risk-free.

• Orange tips are federally required on all airsoft guns sold in the U.S. to help distinguish them from real firearms.
• Age restrictions vary by state and store, but most fields require players to be at least 12–18 years old.
• Eye protection is mandatory, and full-face masks are strongly recommended.
• Always check your local laws. Some states and cities have specific rules about transportation, display, or use in public spaces. You can find more legal info here.

What is a BB Gun?

How BB Guns Operate

Most modern BB guns are powered by CO2 cartridges, housed in the magazine or grip. These pressurized canisters allow for semi-automatic shooting, giving BB guns a bit of that “real steel” feel without actual combustion.

You’ll also find spring-piston models, which are manually cocked before each shot, less convenient for rapid fire, but often more affordable and durable for beginners.

BB Ammunition

BB guns fire .177 caliber BBs, typically made from steel and sometimes coated in copper for rust resistance. They're much heavier than airsoft BBs and can easily ricochet off hard surfaces.

This is one of the biggest differences between BB vs airsoft: airsoft ammo is designed to break or bounce safely, while BBs are hard metal rounds that can cause real damage if misused. Eye protection is mandatory.

Use Cases for BB Guns

BB guns are used for:

• Backyard plinking
• Skill-building
• Indoor ranges

They’re not used in airsoft fields or organized tactical games and shouldn’t be. The higher power and metal projectiles make them unsafe for face-to-face skirmishes.

Safety Considerations for BB Guns

Even though BB guns aren’t classified as firearms, they can still cause serious injury.

• Metal BBs can break skin, damage eyes, or ricochet unpredictably, especially in enclosed areas.
• Adult supervision is a must for younger or inexperienced users.
• Protective eyewear is essential, not just suggested.

Always treat a BB gun with the same respect you'd give any tool that can cause injury.

Legal & Transport Concerns

• Certain cities and states (especially places like New York City or San Francisco) have laws restricting sale, use, or public carry of BB guns.
• When traveling, never pack a BB gun in your carry-on bag. Even in checked luggage, the airline may require it to be unloaded and stored properly.

Some states also require orange tips on BB guns. Bottom line: know your local laws before you buy or transport.

What is an Air Gun?

Pellet Gun Overview

Pellet guns are a type of air gun that fire projectiles. These pellets come in various calibers, but the most common are:

• .177 caliber: Often used for target shooting and competitions.
• .22 caliber: Favored for hunting and pest control due to its stopping power.

Unlike BBs, which are spherical and usually made of steel, pellets are designed for stability and accuracy, particularly over longer distances. This makes them very different in both intent and performance.

Many air guns, including CO2-powered pistols, break-barrel rifles, and pre-charged pneumatic (PCP) models, fall under this category. You can check out available air guns here, including models and compatible ammo.

Intended Uses for Air Guns

Air guns are typically used for:

• Small game hunting
• Pest control
• Precision target shooting

Power and Accuracy

Air guns operate at much higher pressures, which gives them significantly more muzzle velocity. Here's a general FPS (feet per second) range to give you perspective:

• Airsoft guns: 250–450 FPS
• BB guns: 350–600 FPS
• Air guns: 600–1,200+ FPS, depending on model and caliber

Legal Restrictions for Air Guns

Air guns might not require a firearm license in most states, but they still come with their own set of rules, and they vary widely depending on where you live.

• Many states require users to be at least 18 to purchase or operate high-powered models.
• Licensing and permits may be needed if you're using air guns for hunting, especially on public land.
• Local ordinances may restrict discharging air guns within city limits, even on private property.

Some countries (and even some U.S. cities) treat high-powered air rifles like firearms, so before you buy or use one, make sure you’re on the right side of the law.
